使用单元格公式的Apache POI
问题描述:
我与Apache POI工作创造新的专栏,我有一个问题,如使用的两列分裂添加新列,也希望以百分比来获得(%)使用单元格公式的Apache POI
请求的输出
这里是Java代码,
public class ApacheCreatePivotTab
{
public static void main(String[] args) throws Exception
{
XSSFWorkbook wb = new XSSFWorkbook();
XSSFSheet sheet = wb.createSheet();
//Create some data to build the pivot table on
setCellData(sheet);
FileOutputStream fileOut = new FileOutputStream("output.xlsx");
wb.write(fileOut);
fileOut.close();
wb.close();
}
public static void setCellData(XSSFSheet sheet)
{
Row row1 = sheet.createRow(0);
// Create a cell and put a value in it.
Cell cell11 = row1.createCell(0);
cell11.setCellValue("Names");
Cell cell12 = row1.createCell(1);
cell12.setCellValue("utilization_pct");
Row row2 = sheet.createRow(1);
// Create a cell and put a value in it.
Cell cell21 = row2.createCell(0);
cell21.setCellValue("Michal");
Cell cell22 = row2.createCell(1);
cell22.setCellValue("6772.00902935");
Row row3 = sheet.createRow(2);
// Create a cell and put a value in it.
Cell cell31 = row3.createCell(0);
cell31.setCellValue("Michal");
Cell cell32 = row3.createCell(1);
cell32.setCellValue("6118.1434599");
Row row4 = sheet.createRow(3);
// Create a cell and put a value in it.
Cell cell41 = row4.createCell(0);
cell41.setCellValue("Michal");
Cell cell42 = row4.createCell(1);
cell42.setCellValue("5000");
Row row5 = sheet.createRow(4);
// Create a cell and put a value in it.
Cell cell51 = row5.createCell(0);
cell51.setCellValue("Michal");
Cell cell52 = row5.createCell(1);
cell52.setCellValue("5279.50310559");
Row row6 = sheet.createRow(5);
// Create a cell and put a value in it.
Cell cell61 = row6.createCell(0);
cell61.setCellValue("Henry");
Cell cell62 = row6.createCell(1);
cell62.setCellValue("6170.8860759");
}
}
此代码给我我所进行的操作,将其添加第三列一个表
答
要添加第三列
Row row1 = sheet.createRow(0);
// Create a cell and put a value in it.
Cell cell11 = row1.createCell(0);
cell11.setCellValue("Names");
Cell cell12 = row1.createCell(1);
cell12.setCellValue("utilization_pct");
Cell cell13 = row1.createCell(2); // create third column
cell13.setCellValue("After_div and adding %");
若要使单元格的格式更改为数字
Row row4 = sheet.createRow(3);
// Create a cell and put a value in it.
Cell cell41 = row4.createCell(0);
cell41.setCellValue("Michal");
Cell cell42 = row4.createCell(1);
cell42.setCellValue("5000");
Cell cell43 = row4.createCell(2);
HSSFCellStyle styleForNumeric = wb.createCellStyle();
styleForNumeric.setDataFormat(HSSFDataFormat.getBuiltinFormat("0.00")); // format cell to numeric
cell43.setCellStyle(styleForNumeric);
cell43.setCellValue("50.00");
将其舍入为2个十进制数。 –
谢谢,但我想首先在java中使用apache poi库执行单元操作如何在java中执行此操作 –
要创建新列? –
